Types and calculations of the transit of Venus, and the eclipses of the Sun and Moon, in 1769. A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun. A solar eclipse (as seen from the planet Earth) is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and when the Moon fully or partially blocks (occults) the Sun. A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. | |
